HINGE-JOINT.

Application filed September 1, 1909.

T 0 all whom it may concern:

Be it known that I, FRANK lVIarrnnoTi-I, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented a new anduseful Hinge-Joint, of which the following is a specification.

My invention relates to improvements in hinge joints, more particularly,but not necessarily, adapted for use in the construction of umbrellas;and the objects of my improvement are, to provide a simple, inexpensive,

- and easily applied device; to afford a hinge actually locked upon itssupports; to reduce the number and variety of operations heretoforenecessary in constructing and positioning devices of the classdescribed; and to insure against breakage of the parts composing saidjoint. These desideratums I attain by the peculiar construction andapplication of parts herein illustrated and described, like letters ofreference denoting like parts throughout.

Figure 1 is a plan view of the member which is secured upon a rib of anumbrella frame; Fig. 2 a like view of the member which is secured to aso-called rib-brace or stretcher; Fig. 3 a side elevation of thecompleted joint; Fi 4; a front elevation of said joint; and Fig. 0depicts an indentation or oblong slot provided in the metal of said rib,into which is afterward impressed a por tion of the body of said ribmember.

A suitable sheet of metal being provided, it is stamped out as shown inFigs. 1 and 2, and for simplification of description the article of Fig.1 (the rib member) shall herein be designated as part A, and the articleof Fig. 2 (the stretcher member) as part B In the application of part A,lugs C are bent, along demarcation D, D, at substantially right anglesto body portion E, which latter is then encircled about the properportion of rib F, which. operation brings lugs C closely together (Fig.l). Thereafter, said rib, carrying part A, is placed upon a machineadapted to strike or bear upon body portion E at a point just oppositeslot G, and thus said part is positively looked upon its support. Part Bis bent, along line H, H, so as to completely incase an extremity ofstretcher I, its lateral margins J closely contacting, and said part isthereafter actually looked upon its said support by being compressedupon its upper derlying Specification of Letters Patent.

half, said compression simultaneously flattening the incased end of saidstretcher as indicated in dotted outline (Fig. i). It will here benoted, by reference to Fig. 2, that from the peculiar formation of thebody portion K which gradually widens from what may be termed its baseline L to its upper margin N1, the said compression or swaging operationnaturally causes said extremity of said stretcher to become wider atpoint N than at point 0, and obviously it will be impossible for part Bto revolve or to slip upon its said support. Parts A and B being thuspositioned, opposing lugs P of part B fit snugly over and against theexternal face of lugs C and are pivotally secured in that position bythe passage of a rivet Q. through registering apertures R.

From a consideration of the drawing, in view of the foregoingdescription, the objects and advantages earlier set forth will beapparent: the device is simple, easily ap plied, and inexpensive toproduce; there can be no question of the positive locking of the saidparts upon their respective supports, effected through a novelty ofconstruction and by an original method; a reduction of the number andvariety of operations heretofore necessary in constructing andpositioning devices of the class in question is manifest by comparison,for but six (6) steps are necessary to the formation and subsequentapplication of my invention,- namely, the cutting of the two said partssimultaneously with a single stroke of a die; their disposal upon theirrespective sup ports; their locking thereupon; and the final insertionof the rivet; and from the fact that no delicate shoulders, sharpcorners, or other and secondary formations are evolved from the originalblank, thereby enabling me to use the strength of comparatively heavymetal, it may with propriety be said that breakage of my hinge joint isinsured against.

hat I claim as new and desire to secure by Letters Patent is z 1. Adevice of the class described, comprising a member completely incasingan extremity of a brace, said incasing member gradually widening fromits extremity L to its extremity M, the portion of said member adjacentits wider extremity and the unportion of said brace being compressed,and lugs integral With said member in pivotal engagement With a secondmember upon an adjacent rib.

2. A device of the class described, comprising a rib having anindentation, a member completely encircling said rib, a portion of saidmember depressed in register With said indentation, and a second membercompletely incasing an extremity of an adjacent brace, said secondmember gradually Widening from its extremity L to its extremity M,

the portion of said second member adjacent its Wider extremity and theunderlying portion of said brace being compressed, and lugs integralwith said second member in 15 pivotal engagement With lugs upon thefirst named member.
